FYI I cannot get to it today, trees down and storming here.

Right now with my stumbling around it is not even close to Boost and when idling it reads -11.** when the gauge reads 18.**

This is me on the interface.

this is the interface instructions from hpt a long time ago. i have the same module as you but i run the latest beta software so my layouts look different than yours.

according to this diagram here and the aem 30-0306 manual
aem pin 9 (white) ---> hpt location 1,2,3, or 4
aem pin 10 (brown) ---> hpt location 5 or 6

according to your wiring this follows suite. therefore you have a vcm suite calibration error or a power supply issues.
does the gauge have its own power supply and clean ground? clean locations are battery posts.
can you post the most current screen for your calibration settings?

Just checking in guys to let you know I'm not forgetting this. I am side tracked because of other issues, I hope you will be here when I go on the attack again to dial it in.

Thanks

Bumping this thread for anyone else having issues with this. The correct function for the AEM is "(Input /.08) + -20.95" or just transform it into the AEM 30-2131-50 3 bar psia Map sensor option which is what this map sensor really is. The instructions for the scaling were not correct for this particular map sensor and HPtuner makes it a little confusing using a different formula.

Thanks, I did get much closer using the 30-2130-15 predefined but will try the 30-2131-3 if I find it in the list. I'm on Scanner 4.4.2.
